 173 @item How to store the given size so that no significant information is lost?
 174 @item If we store the size in bytes, what if the given size gets over the
 175 MAXUINT64 value?
 176 @item How to interpret sizes entered by users according to their locale and
 177 typing conventions?
 178 @item How to deal with the decimal/binary units (MB versus MiB) ambiguity?

 365 @item Gives your parser great efficiency by packrat parsing.
 366 @item Supports direct and indirect left-recursive grammar rules.

 368 The grammar of your parser can be described in a @acronym{PEG, Parsing
 369 Expression Grammar}.  The PEG is a top-down parsing language, and is similar
 370 to the regular-expression grammar.  The PEG does not require tokenization to
 371 be a separate step, and tokenization rules can be written in the same way as
 372 any other grammar rules.")
